IP Connectivity

An engineer is configuring router R1 with an IPv6 static route for prefix 2019:C15C:0CAF:E001::/64.

The next hop must be 2019:C15C:0CAF:E002::1.

The route must be reachable through the R1 Gigabit 0/0 interface.

Which command configures the designated route?

  • A R1(config-if)#ip route 2019:C15C:0CAF:E001::/64 GigabitEthernet 0/0
  • B R1(config)#ip route 2019:C15C:0CAF:E001::/64 GigabitEthernet 0/0
  • C R1(config-if)#ipv6 route 2019:C15C:0CAF:E001::/64 2019:C15C:0CAF:E002::1
  • D R1(config)#ipv6 route 2019:C15C:0CAF:E001::/64 2019:C15C:0CAF:E002::1
Explanation

Cisco IOS configures IPv6 static routes with the global configuration command ipv6 route, and a route that specifies a global unicast next-hop address can be installed by recursive lookup through the proper outgoing interface. That makes ipv6 route 2019:C15C:0CAF:E001::/64 2019:C15C:0CAF:E002::1 the correct configuration. The ip route command is for IPv4, and config-if mode is not where static routes are created.
